In cultural geography is the theory of the environment that sets certain constraints or limits. Means possibilism denies the influence of environmental factors in human life. The possibilism theory was given by David Le Da Blanche, a French geographer.
Explanation:Humans and the environment have been living together in the ecosystem since ages. Both humans and the environment need to live in hand to maintain the ecosystem. Harm to any one of the two factors lead to destroying the ecosystem. Humans have been exploiting and making changes to the environment to make themselves comfortable according to his will. The agricultural exploitation to manage increased demand of food for the rising population. But man, forget the harm it is causing to the environment . Hence the environment has made certain limitations to save the ecosystem and life on earth. The environment is controlling the harmful effects of human activity on nature. Air pollution, deforestation etc. The environment causes certain natural calamities which keep control on humans. Man might invent many artificial methods to improve life, all its success depends on the response of the environment to the method. Environmental possibilism is required to keep a check on the human needs, preservation of nature and natural ecosystem. Environmental possibilism maintains the normal cycle in the ecosystem It balances all lives which makes man have a better life
Possibilism in cultural geography is the theory that the environment sets certain constraints or limitations, but culture is otherwise determined by social conditions. ... Possibilism in geography is, thus, considered as a distinct approach to geographical knowledge, directly opposed to geographical determinism.
